Issue Details

I'm looking to use my switch matrix in a two-wire 16x16 configuration. Looking at the documentation, it is not clear if this means it can be configured as 16 two-wire inputs and 16 two-wire outputs, or if the inputs and outputs are one-wire and will be distributed as 8 two-wire inputs and 8 two-wire outputs.

Solution

A 2-Wire 16x16 Matrix Topology means that the card will be configured as a 16x16 matrix, where each of the 16 inputs and 16 outputs will have two terminals for positive and negative connections.

For more details, refer to Topologies and N-Wire Switching Modes in the NI-Switches Help.
